PHP script can't work with autoloaded classes

Question

The UsersView class object can't be loaded with the custom autoloader, finishing the PHP script with the following error. What would be the solution?

Fatal error: Uncaught Error: Class 'UsersView' not found in /Applications/XAMPP/xamppfiles/htdocs/solent/common/registration/pendings.php:4 Stack trace: #0 {main} thrown in /Applications/XAMPP/xamppfiles/htdocs/solent/common/registration/pendings.php on line 4

Project structure:

classes
   |_____ UsersView.php

common
   |_____ autoloader.php
   |_____ registration
               |_____ pendings.php

Pendings.php script

include("../autoloader.php");

$pendingsView = new UsersView();
$rows = $pendingsView->getAllUsers();

Autoloader.php script

spl_autoload_register('myAutoLoader');

    function myAutoLoader($className) {
        $path = "../classes";
        $extension = ".php";

        $fullPath = $path . $className . $extension;

        if(!file_exists($fullPath)) {
            return false;
        }

    include_once $fullPath;
